SELF-CLOSING TAP.

SPECIFICATION forming part of Letters Patent No. 297,691, dated April 29, 1884.

- Application filed March 12, 1883. (No model.)

To all whom it may concern:

- Be it known that I, FRANCIS HYDE, of I the city of Toronto, in the county of York, in the Province of Ontario, Canada, .have invented a new and useful Self-Closing Tap; and I do hereby declare that the following is a full, clear, and exact description of the same.

My invention relates to that class of taps which are used by plumbers in the fitting up of bath-rooms, water-closets, wash-basins,"and for general purposes where common taps are used.

My invention has for its object the prevention of the waste of water which takes place from the common taps being left open, and,

besides causing a loss ofwater, the apartments in which the taps are placed are frequently flooded from the same cause, and considerable damage done thereby.

In the accompanying drawings, Figure l is an elevation, andFig. '2 a sectional elevation, of my self-closing tap. Fig. 3 is a sectional elevation of the valve and stem, and also the valve-seat, with metallic washer above the same. Fig. 4; is a cross-section of the valvestem, through that portion which slides up and downi through the.valve-seat, which is also shown in this'figure. Fig. 5 is a plan view of the base of my tap.

'Similar letters of reference indicate similar parts in all the views and in this specification.

A represents my self-closing tap; a, the button on top of valve-stem; b, the stem, the

lower portion of which is three-sided, making provision for the water to pass through between the stem and the seat,,as shown in Fig.

' 4; c, a gland of the stuffing-box in the upper end of the tap; at, a spiral spring located between the button and the gland, for the purpose of assisting the closing of the valve; 6, the stuffing-box, which is filled with soft greased packing; f, the body of the tap; g,

the seat It.

the delivery-nozzle; h, the valve closing upwardly on a flat seat, but tapering downwardly for the easier opening thereof, which is easier pressed down than with a fiat surface; h, thevalve-seat, of prepared rubber or other suitable material; h, a metallic flanged washer located above the seat, which is pressed down on the same, and makes a solid body for the face of the valve to act upon; 2', the base of the tap, which is secured, in the present case, on

a basin-table; J, athreaded stem, which passes through the table, and on which a nut is placed and secures the tap thereon.

My tap is intended to be placed in others besides a vertical position. The valve will operate as well as in a vertical position.

The operation of my self -closing tap, as

shown in the drawings, is as follows! The tap is opened by pressing down the button a,

which also presses down the valve h, leaving an opening between the valve h and The stem 6 being three-sided at this part, as hereinbefore described, the water rushes through at these three "points, and is discharged from thedelivery-nozzle. On removal of the finger from, the button a, the pressure of the water on the back of the valve,.with a very slight assistance from the spiral spring d, will immediately close the valve of the tap, and it will remain closed till again required.

- Having thus described my invention, I claim- In a faucet, the valve-body A and threaded stem J combined with the valve-stem b, triangular in cross-section and carrying the upwardlyseating valve-h, valve-seat h, and metallic flanged washer h, the whole arranged substantially as set forth.

FRANCIS HYDE.
